I’m working on a research project wherein we are trying to solve a problem very similar to VLBI delay. We have two radio receivers, and we know their locations. We also know at what time one receiver detected a signal, and the coordinates of it’s beam-pointing center. We want to determine at what time the second receiver should’ve seen the signal.

I understand in principle how VLBI delay is calculated; I’ve seen a few different formulas, such as the dot product of a vector between the receivers, and between the receiver and the source but practically speaking, how would I actually go about producing numbers?

  • $\begingroup$ Yes this task needs a more definitive solution than what I gave before. Can you use Python? Or are you planning to use a spread sheet or pencil and paper, or do you need a website? I am not sure I can post a complete answer but probably someone can. But it will be helpful to them if you can mention which resources or calculation techniques you have available. $\endgroup$ – uhoh Jul 14 '20 at 9:51
